This is a joint for a spirally reinforced hose, in which a reinforcing body made of synthetic resin (band-shaped, wire-shaped) is wound spirally, and is used for the connection part of equipment to which the hose is connected.

で構成されている。(Prior art) A conventional general hose joint has a joint body that includes a bamboo-shaped nipple part into which a hose is fitted, and a male thread part into which a hose nut for tightening a hose is screwed. and a hose nut that tightens the hose fitted to the nipple.

部外周面とホース内面との間に隙間が生じるのを確実に
防止し、液体、気体の漏れを防止すると共に、ホースの
族１ノを防止し得るようになっている。The above-mentioned hose joint is suitable for resin hoses and rubber hoses with smooth inner and outer surfaces, and reliably prevents gaps from forming between the outer circumferential surface of the nipple and the inner surface of the hose. In addition to preventing gas leakage, it is also possible to prevent hose failure.
ところで、最近はホースの可撓性及び耐圧性を向上させ
るものとして金属製又は合成樹脂装の補強体をホースの
肉厚内又は外表面に１本又は複数本を螺旋状に巻回した
螺旋補強ホースが種々開発されている。By the way, recently, as a way to improve the flexibility and pressure resistance of hoses, helical reinforcement, in which one or more reinforcing bodies made of metal or synthetic resin are spirally wound inside the wall thickness or on the outer surface of the hose, has been developed. Various hoses have been developed.

態を生じるものである。Therefore, the outer and inner surfaces of this spiral reinforcement 11 are uneven, or one of the inner and outer surfaces is uneven, and the unevenness forms a spiral shape that extends over the entire length of the hose in the longitudinal direction. Appears continuously over a period of time. Therefore, when this spiral reinforcing boss is connected to the above-mentioned conventional hose joint, a gap is created between the outer surface of the nipple and the inner surface of the hose, and the transferred fluid (TE body, gas) may leak, get stuck, or squirt out. It is something that causes a situation.

補強体とは交叉して一部分しか接触せず隙間が生じるた
めである。The reason for this problem is that since the reinforcing body is wound in a spiral, it is difficult to tightly tighten the hose nut from above, and furthermore, when the top of the spiral reinforcing body is pressed, the nipple part becomes independent. This is because the ring-shaped peak and the reinforcing body intersect and only partially contact each other, resulting in a gap.
そこで、最近はこうした螺旋補強ホースに確実に接続で
き、流体の漏れ及びホースの仇は等を生じないところの
ボース継手の出現が望まれている。Therefore, recently there has been a desire for a Bose joint that can be reliably connected to such a spirally reinforced hose and that does not cause fluid leakage or damage to the hose.

On the inner surface of the sleeve that is wrapped around the outside of the hose, a protrusion is formed at a position corresponding to the rosette and engages with one or more pitches of the reinforcing body, so that the protrusion on the inner surface of the sleeve is When the sleeve is contracted in the ↑ force direction due to the tightening of the hose neck 1-, the above-mentioned protrusions are fitted into the grooves between the helical reinforcing bodies and come into contact with the resin or rubber part constituting the hose. Press the part or rubber part to make it stick to the packing. At this time, since the protrusions are engaged with the spiral grooves by at least one pitch or more, the entire circumference of the hose comes into close contact with the packing, producing a complete sealing effect.

確実に防止できる。(Effects of the Invention) As described in detail above, the hose joint according to the present invention includes a gasket provided on the nipple portion, a protrusion spirally provided on the inner surface of the sleeve in correspondence with the gasket, and a radial direction of the sleeve. Since it is composed of hose knots that can be contracted, the reinforcing body is wrapped spirally around the inside or outside of the hose.
When a hose with spiral irregularities formed on the inner and outer surfaces is fitted into the nipple, a sleeve is covered on the outside and the hose slit is tightened, the sleeve contracts in the radial direction and the protrusions attach the hose to the gasket. Pressure adhesion u1 provides a tight sealing effect, and can reliably prevent leakage of fluid (liquid, gas) and disconnection of the hose.
